| 摘 要： | 实现两种颗粒混合物的竞争式聚集行为的二维仿真模拟,编程时考虑颗粒与颗粒、颗粒与侧壁、颗粒与中央挡板以及颗粒与底板的碰撞.模拟结果表明:振动强度较小时,颗粒最终聚集到起初小颗粒多而大颗粒少的右室;振动强度较大时,颗粒最终聚集到起初大颗粒多而小颗粒少的左室;振动强度很大时,颗粒呈均匀分布状态,模拟与实验定性符合良好. |

| Abstract: | Two-dimensional simulation competitive clustering behavior of the mixture composed of two sorts of granules was implemented.The collisions among particles,between particles and side walls,mid wall,and bottom were taken into consideration.It was shown by the simulation results that,for mild shaking strength,the particles clustered in the right compartment,for moderate shaking strength,the particles clustered in the left compartment,and for sufficiently strong shaking,a uniform distribution was found,being qualitatively accordant with the experimental results. |
